Abstract

The remove-and-replace method is one method used to overcome soft soil problems. This research aims to determine the effect of replacement depth on the amount of settlement and the value of the safety factor of the embankment. The research was carried out by comparing the initial conditions with replacement depths of 0.5, 1, 1.5, and 2 meters. Analysis was carried out using the finite element method with the help of PLAXIS 2D software. From the analysis results, it was found that the largest decrease in settlement value for 2-meter replacement was 22.7% for DB-2 and 16.1% for DB-13. The 2-meter replacement also results in increased safety factor values for the DB-2 and DB-13.

Abstract

Earthquake resistant construction planning is very crucial in Indonesia, considering that most of Indonesia's territory is located in areas with moderate to high earthquake intensity. Especially the construction of high-rise buildings in the city of Jakarta which are built with irregular building plans. Therefore, development in the city of Jakarta must consider the earthquake forces that will occur on buildings to minimize losses caused by irregular building shapes. In this research, the irregularities of a T-shaped plan building will be planned, using a building split analysis method called dilatation, which will be modeled into 5 structural models, namely the first is a complete T-shaped plan or without dilatation, while the second and third models use the two-column dilatation method 1a and 1b, the fourth and fifth models use the cantilever dilatation method 1a and 1b. All models are designed with a special moment resisting frame system (SRPMK). This analysis aims to determine the earthquake force, structure period, and displacement of the structure. From the results of the structural analysis, the difference in the value of the structural period, the displacement between floors that occurs in dilated buildings, is obtained.

Abstract

Earthquakes are defined as vibrations originating from the movement of tectonic plates beneath the earth's surface, with the greatest impact on building damage, especially high-rise asymmetrical buildings that have a high potential for horizontal displacement in the building structure. For this reason, it can generally be overcome by using dilatation in order to reduce building irregularities. In this analysis process, the building model is divided into 5 structural models, namely a model without dilatation (intact with a U plan), with two column dilatation divided into 2 parts called buildings A, and B, and cantilever dilatation divided into 2 parts called buildings A and B. All models are designed with a truss system. All models are designed with a special truss system. From the results of the structural analysis, it is found that the dilatation greatly affects the deviation between floors, the structural vibration period and the p-delta that occurs in the building. The internal forces that occur in columns and beams also show significant results, especially in columns with structures without dilation compared to using dilation.

Abstract

old-formed steel has emerged as a prominent material in modern construction due to its excellent structural performance, cost-effectiveness, and sustainability. Hollow structural sections made of cold-formed steel have garnered significant attention due to their favourable strength-to-weight ratios and versatility in construction applications. In this research, the cross-section of cold-formed steel hollow structural sections will be analysed as a structure that receives a combination of compressive and bending loads. Numerical analysis was carried out using the finite element method with the help of ABAQUS software to obtain the buckling behaviour and cross-sectional capacity. The cold rolled steel regulations in SNI 79712013 or AS/NZS 4600 will be compared with numerical results to see the level of performance of the code in the case of hollow structural sections. Numerical testing and cross-sectional capacity calculations refer to existing references in the literature.

Abstract

Earthquakes are one of the factors in the collapse of a building structure because vibrations cause movement in the building structure above it, building structures with asymmetrical shapes tend to experience displacement or movement of structural elements higher than structures with symmetrical shapes, asymmetrical building shapes, for example, such as U, L, T and H-shaped building plans with the dilatation method aiming to separate the building to be simpler and make the building more symmetrical. In the analysis of the building structure, 5 models are modeled, a model without dilation (H-shaped plan), a two-column dilation model 1A, a two-column dilation model 1B, a cantilever dilation model 1A and a cantilever dilation model 1B. The results of the structural analysis with the two-column dilation and cantilever dilation methods affect the value of the structural period, the deviation between floors and the p-delta value because the building becomes more symmetrical and simpler.

Abstract

Kebutuhan energi terbarukan di Indonesia sangatlah penting, saat ini sumber energi terbarukan porsinya relatif kecil. BPPT ( Badan Pengkajian dan Penerapan Teknologi) dalam kegiatannya melakukan pembangunan pilot plant Biogas Pome setara 700 kW berkerjasama dengan PTPN V (PT. Perkebunan Nusantara V) dengan sistim tangki berpengaduk secara kontinu yang mana hasil gas tersebut dimanfaatkan sebagai bahan bakar boiler pabrik PMKS di sei pagar. Desain pondasi tangki reaktor dengan kapasitas 2000m3, telah dilakukan dengan menggunakan perhitungan fix head dengan diameter pile 60cm type B dengan jumlah 32 pile dengan kedalaman 12m dikerjakan tahun 2018. Diameter rencana tangki reactor direncanakan berukuran 16.8m dengan ketinggian 9m, dengan beban tangki sekitar 2174.2ton. Sedangkan sekarang terjadi perubahan desain tangki dengan diameter 14m dengan ketinggian 16.8, dimana tinggi pome di 16.1m, dimana beban tangki menjadi 2639.1 ton, dimana berdasarkan koreksi tersebut, analisa pile masih memenuhi sedangkan untuk puching shear perlu di lakukan pertebalan, dimana d' sebelumnya 70cm, sekarang dibuat pile cap 1.2 m dengan d' sebesar 80 cm , dengan tebal mat 60cm.
